CROSS-LINE BUCKLE.

SPECIFICATION forming part of Letters Patent No. 777,940, dated December 20, 1904.

Application filed August 9, 1904. Serial No. 220,135.

To all whom it may concern.-

Be it known that I, LYMAN E. ORANDALL, a citizen of the United States, residing at Stanwood, in the county of Mecosta and State of Michigan, have invented certain new and useful Improvements in Cross-Line Buckles, of which the-following is a specification.

This invention provides an improved form of buckle particularly adapted as a means for attaching cross-lines to long lines of harnessreins, though useful in any like capacity wherein it is desirable to provide a connecting device which admits of ready detachment and adjustment of strap parts relative to each other.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for-effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in Which- Figure l is a perspective view showing a buckle applied. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a detail view of the buckle, bringingout more clearly the exact construction thereof. Fig. 5 is a perspective View, the frame being of a modified construction, the cross-bar being thrown upward.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The buckle in its general organization consists, essentially, of the frame 1, and this frame is preferably formed from a plate of sheet metal or the like, to one end of which is permanently attached a cross-line 2. cross-line 2 passes through the opening 3 in the end of the frame 1, andthe long line 4 is secured adjacent the opposite end of the frame. The means for attaching the long line 4 and for adjusting the said line consists of a transversely-disposed cross-bar 5, pivoted to one side of the frame and having interlock- The ing connection with the other side thereof. The cross-bar 5 is provided between its ends with a tongue 6, adapted to engage in openings 7 in the long line, and this tongue is preferably made by bending the cross-bar at a point between its ends. Projected from one end of the cross-bar 5 is a pintle member 8, which extends longitudinally ofthe frame 1, being received in a longitudinal bearing 9 upon said frame. The bearing 9 is preferably formed by rolling one side of the frame in such a manner as to readily receive the pintle member 8, above mentioned. To prevent displacement of the pintle member 8 from the frame, the end portion thereof is bent at an angle, as shown at 10.

From the foregoing it will be readily seen that the bar 5 is pivotally mounted so as to swing transversely of the frame 1, and in order to positively hold said bar with its tongue in engagement with the long line 4 a lock extension 11 is projected therefrom, being adapted for interlocking cooperation with the frame. The extension 11 projects from the end of the cross-bar opposite that provided with the pintle member 8, and this extension 11 is provided with a nib 12, formed by bending the extremity thereof, said nib being adapted to pass through an opening 13, provided therefor in the frame. To positively hold the extension 11 against and in interlocking engagement with the frame 1, a latch device is utilized, and said device comprises a latch-plate 14, pivoted to the upper side of the frame 1, as shown at 14, said plate being adapted to engage over the end portion of the extension 11 to hold the nib thereof within the opening 13. The plate 14 has a projection 15. which engages in an opening in a flange 16, formed at the adjacent side of the frame. The flange 16 is preferably formed by bending a longitudinal edge portion of the frame 1 upwardly. The normal position occopied by the latch-plate 14 is such as to hold the same in engagement with the flange 16, and thus normally retain the cross-bar 5 in operative position.

secured to, the upper side of the frame 1, and this spring has one end rigidly attached to the frame, as shown at 18, the other end engaging A V-shaped spring 17 is and bearing against the latch-plate 14, as shown at 19, to hold the latch-plate in the normal operative position above described.

The buckle is comparatively simple in general form, and in operating the same it is only necessary to press the latch-plate 14 laterally against the tension of the spring 17 and the projection of said latch-plate will be disengaged from the flange 16. The above having been accomplished, the end of the lock extension 11 is uncovered, and the cross-bar 5 may be readily pushed upwardly from the frame by a pivotal movement thereof. When the cross-bar is pivotally operated, as above mentioned, the long lines may be quickly disengaged from the tongue 6 or adjusted relative to said tongue in a manner which will be clearly seen. In detaching the long line it is unnecessary to thread the same through the buckle, which disadvantage is present in many of the ordinary types of buckles noW in use. The latch-plate 14 is provided with an upwardly-projecting flange 20, which forms a member by which said plate may be easily grasped and operated.

As shown in Fig. 5, the cross-line 2 is attached to the frame 1 by a rigid tongue 25,

projected upwardly therefrom. Loops 26 upon the frame assist in holding the cross-line 2 engaged by the tongue 25.

Having thus described the invention, what is claimed as new is In a buckle, the combination of a frame provided at one side thereof with a longitudinal bearing and at the opposite side with a longitudinal flange, a cross-bar mounted upon the frame, a pintle member extended from said cross-bar at one end thereof and mounted in the longitudinal bearing aforesaid, a lock extension projected from the opposite end of the cross-bar and provided with a nib received by the frame, a latch-plate pivoted to the frame and engaging the flange thereof and the lock extension of the cross-bar, and a spring attached to the frame and bearing against the latch-plate to normally hold same in engagement with the lock extension.

In testimony whereof I affix my signature in presence of two witnesses.
